[comp.protocols.tcp-ip] TCP Optimizations/Enhancements

gary@dvnspc1.Dev.Unisys.COM (Gary Barrett) (09/13/89)

I have seen mention of the "Nagle algorithm" to improve TCP
performance.  And I've seen reference to TCP enhancements by Nagle,
Jacobsen and Karn.

Would someone out there post a summary of these TCP enhancements?
What do they do?  

Thanks.

Gary:

    Instead of trying to explain all the concepts, here's the list
of papers.  They are all quite readable, and it is generally better
to get things from the source...

    Nagle: There are two algorithms, and thus, two papers. RFC 970
    (which also appeared in IEEE. Trans. Communications, Vol 35, No. 4)
    and RFC 896.

    Karn: P. Karn and C. Partridge, Improving Round-Trip Time Estimates
    in Reliable Transport Protocols.  Proc. ACM SIGCOMM '87, pp. 2-7.

    Jacobson: V. Jacobson, Congestion Avoidance and Control, Proc.
    ACM SIGCOMM '88, pp. 314-329
